it first went like this I installed a v-afc2 in the car all ways fine execpt red lining at 6500 so I took it til I get up to the shop, so anywas everything wire and all back to normal no no v-tec and still red line at 6500, oil level is good. I've tryed to reseting by removing the battery cable and nothing. anything I over looked

 

Someone correct me, but isnt it in limp mode?

 

your car is possibly in limp mode right now. This is a problem that has happened to me before with my first Prelude, and has happened to several other members on this board

 

what the hell is limp mode?? lol

 

limp mode lol how long does limp mode last four

 

sumthin cant b rite, re check ur wiring. cel on ??

 

Limp mode is when your ECU detects a problem, and decides to put your car "on a leash" to minimize further damage. Different ECU's handle this differently, usually they retard the timing, add more fuel, lower the rev limit, disable vtec, etc. This can be triggered by things such as a broken MAP sensor, low oil, excess knocking, etc, or by bigger problems. Either way, the first thing to do, is to check your CEL code.

It goes away when you fix what's broken.

 

cel code ?????

 

CEL = Check Engine Light
Code = Code thrown by the ECU, indicates what error number you have

 

Short out the diagnostic cable (location depends on the make/year of your car)

Put your key in, go to I
Watch CEL light.
Long flashes = 10's digit
Quick flashes = 1's digit

That's the number for your error, I strongly suggest you find a Helm's Manual for your car. Or, use the mighty power of google to find what your error means.

 

o ok the it was said threw me off yesterday it was a 12, 17 and 22. code 12 comes on after i start, egr. forgot 17 and 22 I've checked the connects over and over and my oil level is good.

so today I reset the ecu again and just let the car til fully warm and just got code22

 

code 22 is a knock sensor i believe?

 

Make sure your car is fully warmed up....

jk

 

22 = vtec presssure switch.

be sure that the wiring is right. Especially at


A26----blk/red------VTEC Pressure Switch (GND) if you car is OBDI
C15---blu/blk------VTEC Pressure Switch if you car is OBDII

 

code 22 is the VTec Oil Pressure Switch

 

Check your wiring that you used and spliced for the VAFC, that should be your problem.

if the car worked right before you installed the vafc then obviously you screwed up the wiring. sounds like formt he cod eyour getting that the wire you specifically mesed up was the vtec presure switch. check all your wiriing and if you have to remove the damn vafc so you can figure out the problem.,

edit : https://honda-tech.com/zerothread?id=830163 &lt;-- that is my offical why vtec doesn't engauge..

also the car is not in limp mode, 6500 is a preset ecu limit for the car when vtec doesn't engauge.. true limp mode is around 5k limit sometimes lower

 

I would go over those wires. My vtec pressure switch was the thing not working on mine.

 

ECU is limp my friend.

 

well after a two weeks of this here limp mode, I put the afc back on just to see if v-tec works and it did but still stops me at 6500

 

As I said, check and double check that wiring, most likely it is faulty wiring.

 

Even if there is no cel he still needs to check wiring.

like i said your not in limp mode, the ecu is runing fine but vtec requirment arn't being met so the ecu set a 6500 rpm rev limit. the afc forces the solinoid to engauge even though per the ecu the basic requirments for vtec have not been met. so you afc opens the solinoid and the ecu brickwalls you at 6500 because something is still not right.

please everyone stop saying he is in limp mode he is NOT!

 

well I took the afc back off the car, checked the wires and oil level made sure all looked good. Let the car warm up til the fan kicked on a few times no codes came on til I drove the car and the only poped up was 17. I thought 22 would of came on since v-tec was no where to be found

dude did you even bother to read the link i posted? , code 17 is the vss , if something is wrong with the vss then there is no VTEC!

have you been noticing problems with your speedo?
